Chris - honestly, you should see the state of my car after the end of an average day, I'll try and take a pic but its normally covered with at least half a dozen separate bird shits. They're not little ones either, I swear half the birds round Southampton have got diahorrea!

Its like I said above though, modern carwashes are fine, I used the same one for a couple of years on my 206 and there were no marks on the paint whatsoever. I have better things to do, frankly, than spend half my weekend cleaning the car...
